The Soyuz 4 crew has toured several other JSC facilities this week, with yet others scheduled. The crew members will launch in late April from the Baikonur Cosmodrome, Kazakhstan, to deliver a fresh Soyuz spacecraft to the station for use as a lifeboat. After spending about a week aboard the outpost, they will return to Earth aboard the Soyuz spacecraft now attached to the station.
